Resident Evil 5 Trophy help & question!?

How do you get the 3 hidden trophies? (the black trophies) %26amp; i have a question. I was playing Resident Evil 5 on versus mode and i swear the other team was cheating some how!!! My partner and I killed all 3 executioners we had like 50,000 something and the other team had like 30,00 and at the last few seconds they magically went from 30,000 to 100,000!!!!! HOW DO THEY DO THIS?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!? T-TResident Evil 5 Trophy help %26amp; question!?
i'll edit this later with the hidden trophies and how to get them...

versus mode scores don't get added on till the combo has finished so if the other team got like a 50-60 combo that extra score would explain the jump.

o.k. the hidden trophies are...

the platinum(get all other trophies-you don't need the trophies for dlc)

War hero (for completing the game on profesional)

****SPOILER****

and Bad blood (you get this for causing wesker to leave before the 7 minute deadline-by inflicting a set ammount of dammage to him---in the fight after you take the mind control device off Jill)

two other trophies you may not have which caused me confusion are

Heart stopper(stab a licker ss in the heart when it is knocked on its back (context sensitive action) (not wesker like i thought lol)

and

Masters of removing (for this when you remove the device off Jill you have to be playing with someone else and you both have to partisipate in the final removal)(this cannot be unlocked in the single player)
